>> translator: well, was the train really continuously moving or did it actually stop once and then start operating again? that part is still unclear. either way, the signal safety design is supposed to make the train stop. the fact that the train moved despite that indicates there may have been some human involvement. >> translator: and what can you tell us about the technology levels of the high speed railway in china? >> translator: at least in terms of research and development and the basic research, i believe they're very advanced. when you take man power or a budget, they have an abundance of both and far exceed what japan has. so their basic capacity is very high, but they have no experience in dealing with anomalies. >> translator: so they haven't conducted proper simulations.
